MARGARET E. LEE, OF OAKLAND, CALIFORNIA.

SPIKE PULLER.

Application filed November 10, 1923.

To all whom it may concern:

Be it known that MARGARET E. Lnn, a

citizen of the United States, residing at Oakland. in the county of Alameda and State of California, has invented certain new and useful Improvements in Spike Pullers, of which the following is a specification.

My invention is an improved spike puller, particularly applicable for removing the spikes from railroad ties.

The object of my invention is to provide a spike puller which will grip the spike at any point on the shank. thereby drawing the spike from the wool without bending it, thus enabling said spike to be reused.

Another object is to provide a spike puller, which is simple in construction, and inexpensive to manufacture.

Referring to the annexed drawing in which 1y invention is illustrated:

Figure 1 is aside view of my spike puller.

Figure 2 is an enlarged fragmentary side view of the same.

Figure 3 is a fragmentary front view of my spike puller.

Figure is a bottom view of the same.

Figure 5 is a sectional view taken on the line of Figure l.

Figure 6 is a fragmentary front view of 30 my puller with the jaws removed.

Figure 7 is a view similar to Figure 3, with the jaws raised and spread.

Figure 8 is a rear View of one of the jaws.

Referring more particularly to the drawing, the elongated handle 1 has an angularly positioned chisel 2 at one end and a pair of arms 3 and 4 at the other end thereof. The lower edges of the arms 3 and 4e are curved as at 5 and they meet at the rear to form the heel 6. The inner surfaces of the arms 3 and 4 each converge downwardly, the purpose of which will be further described.

Serial No. 673,930.

A pair of jaws 7 and 8 are positioned between the arms 3 and l, and are pivoted on a bolt 9 which extends through the arms. A bolt 10 extends through the arms 3 and eland through slots 11 in the jaws 7 and 8, thus limiting the vertical movement of the jaws. A spring 12 is positioned between the handle and the jaws 7 and 8 to urge the jaws downwardly. vThe outer walls of each of the jaws 7 and 8, which contact with the inner surfaces of the arms 3 and 4:, diverge upwardly as shown at 13, which is opposite to the slope of thesaid arms. Thus when the jaws are moved upwardly against the spring 12, they will follow the inner surfaces of the arms 3 and l and spread apart as shown in Figures 4-, and 7 and grip the spike at a new point. The lower surfaces of the jaws 7 and 3 are curved as at let to conform with the curve 5 of the arms 3 and In operation the handl l is moved forward to backward on the surface 5 to raise and lower the jaws 7 and 8 as described. These jaws are each provided with spike engaging recesses 15 on the adjacent edges thereof.

Having described my invention, I claim:

A spike puller comprising an elongated handle, a pair of arms formed on the lower end of said handle, a pin between the arms, and a pair of jaws having apertures therethrough pivoted between said arms and a spring engaging the rear of said jaws to urge them downwardly, each of said jaws having slots formed therein and a second pin between the arms extending through said slots, and into the arms, to limit the movement of said aws.

In testimony whereof I affix my signature.

MARGARET E. LEE.
